Since the 1980s, STOBER has specialized in the development of planetary gear units, the premier class of drive technology!
At the end of 2019, we presented the 3rd generation of planetary servo gear units, bringing drive solutions that are the most compact on the market for their performance range and enormous variety of combinations and options!
STOBER planetary gear units score points above all for their exceptional performance, torsional backlash stability and ruggedness. Alongside that, the excellent housing and gearing quality ensures high acceleration torques and also the highest running accuracy and precision.
What’s more, our planetary gear units have an impressively flexible interface technology. Not only can the gear units be combined with different STOBER motors via direct attachment, they can also be attached to all third-party motors in any size using variable adapters.
As another advantage, you can also select the right bearings for the application you need. With our enormous variety, we give you all the options in the design phase to put together exactly the right drive solution for any application.
STOBER planetary gear units are ideal for machine tools and packaging machines as well as applications in automation and robotics.
High-performance. Precise. Perfect fit.
P: For high precision and smooth operation.
The decisive characteristic of the P series planetary gear unit is the high-quality helical gearing that gives the gear unit smooth operation and backlash stability that is second to none.
Another outstanding property is its extremely high efficiency. Due to the very low frictional torques, this series is ideal for continuous operation and high-speed applications.
P gear units are available as compact, directly attached planetary geared motors in either the servo or Lean version.
Maximum flexibility: The gear units can be attached to all common synchronous servo motors by suitable adapters.
PH: For the highest precision and performance
The PH series planetary gear units are high-performance servo gear units with increased torsional and tilting stiffness.
Their inner workings are distinguished by our proven, high-quality helical gearing. The output shaft is designed as a flange.
The gear units are ideal for drive solutions that have the highest requirements for rigidity, precision and reliability.
PH gear units are either available as directly attached, compact planetary servo geared motors or they can be attached to all common synchronous servo motors by suitable adapters.
PHQ: Quattro power for maximum power density
Quattro power stands for an innovative 4-planet system!
PHQ is a precise servo gear unit featuring high-quality helical gearing as well as the highest torsional and tilting stiffness. For maximum torque.
It is also especially ideal for drives in pick-and-place applications and is the perfect solution for tight installation spaces.
PHQ gear units are either available as directly attached, compact planetary servo geared motors or they can be attached to all common synchronous servo motors by suitable adapters.
PHV: For large gear ratios
PHV – a precise high-performance servo gear unit with proven high-quality helical gearing as well as very high torsional and tilting stiffness.
The gear units are very short, which is perfect for tight spaces. And they are especially ideal for large gear ratios.
PHV gear units are either available as directly attached, compact planetary servo geared motors or they can be attached to all common synchronous servo motors by suitable adapters.
PE: The attractive economy variant
This series is a highly cost-effective variant of the STOBER planetary gear units with high performance. It also has the helical gearing that is typical for STOBER, low noise development and the best smooth operation. It’s a unique feature on the market in this price and product class.
Especially in combination with the STOBER IE5-classified Lean motor, you get an unbeatably compact and economical unit!
STOBER PE gear units can be used for efficient applications in the fields of automation and robotics.
With SERVOsoft®, you have a tool at your fingertips that lets you design your drive systems with precise scaling in just a few steps. Electrical as well as mechanical design, and simple and fast at the same time.
Planetary gear units for highly dynamic applications.
“We work with STOBER because the wide selection of planetary gear units always gives us the right solution for all kinds of different servo tasks. We also appreciate the good advice and support and especially how quick it is. Working together with STOBER is always very enjoyable and productive.”
